I see you want to promote Android Apps.
There's a problem with that, Spam.
These forums are very clean of spam posts that promote web sites, software, and so on for advertising purposes only and not where they may help other members here with their technology problems and questions.
So, feel free to help others, but please re-read Forum Policy about those things that get posts deleted.
I have joined this forum newly, and wants to promote and android app.. any suggestion..PLs...!
